Definitions

  • the present invention relates to an image file system, and more particularly to an image file system for storaged and retrieval of a large amount of image information.
  • microfilm systems have been employed for storage and administration of a very large amount of non-code information (image information).
  • image information image information
  • the microfilm is featured by economy, archival storage ability, high resolving power and high input speed allowing a large amount of copying operations at a high speed, and is suitable for efficient storage and administration of file information increasing year after year.
  • a reader-printer typically illustrated in Fig. 1, wherein a light beam from a light source 1 is transmitted by a microfilm 2 and a lens 3, and is reflected by a fixed mirror 4.
  • a movable mirror 5 is positioned at A, whereby the light reflected by the fixed mirror 4 is projected onto a screen 6, thus forming the image of the microfilm onto said screen 6.
  • the movable mirror 5 is moved to a position B, whereby the reflected light from the fixed mirror 4 is projected onto a photosensitive paper 7.
  • the photosensitive paper thus exposed is developed in a developing station 8 and discharged as a hard copy.
  • FIG. 2 shows a microfiche system as an example wherein microfiche films 10 are stored in a determined order in a magazine 9.
  • an address A is entered from an input unit such as an unrepresented keyboard.
  • a retrieval unit 11 rotates the magazine 9 and stops it at a designated position.
  • an unrepresented drive unit extracts a microfiche film 10 from the magazine 9 and properly positions the desired frame.
  • a light source 12 is truned on, and the emitted light beam is transmitted through a lens 13, the desired frame of the microfiche film 10 and a lens 14 and enters a half-mirror 15. After reflection by the half-mirror 15, the light beam is transmitted through a lens 16 and is projected on an unrepresented optical screen, thus forming thereon the image of the desired frame.
  • the light beam transmitted by the half-mirror 15 is converted into electrical signals by a photoelectric sensor 17, and electrical signals are subjected to suitable process such as binary encoding and amplification in a signal processing unit 18 and are released as image data D.
  • the photoelectric sensor 17 performs scanning in a direction indicated by an arrow by means of a scan control unit 19, thus converting the image information of the entire frame into electrical signals.
  • the image data D thus obtained from the desired frame are supplied to an unrepresented hard copy unit or an unrepresented facsimile transmitting unit.
  • the photoelectric sensor 17 can be conveniently composed of a CCD linear array sensor. Naturally the above-mentioned scanning drive is dispensed with when a two-dimensional area sensor is employed.
  • Fig. 3 shows an example of the microfilm file in which the microfilm is formed as a rolled film.
  • the function in this case is almost same as in the microfilm file shown in Fig. 2, except that a microfilm 20 contained in a cartridge 21 requires a somewhat different driving process for retrieval.
  • Fig. 4 is a block diagram showing an example of the conventional electronic film system, composed of a document reader 22, a printer 23, a work station 24 and a memory 26, all connected to a controller 27.
  • An index file 25 is connected to the work station 24.
  • the document reader 22 utilizes for example a charge-coupled device (CCD), and converts a document by raster scanning into electrical signals, which, after suitable processing such as amplification and binary encoding, are stored in the memory 26. It is also possible to store a document prepared in the work station 24, or information entered from an unrepresented facsimile. In this manner the necessary documents can be stord in succession in the memory 26.
  • CCD charge-coupled device
  • the capacity of the memory 26 should naturally be as large as possible.
  • an optical disk memory of a diameter of 30 cm can store non-code information approximately corresponding to about fifty books, or a small bookcase.
  • the index of said document is simultaneously stored in the index file 25.
  • a keyword, for example, of the document is entered through the work station 24. Then reference is made to the index file 25 and the desired document is read from the memory 26 and released as a hard copy in the printer 23.
  • the printer 23 can be an electrostatic printer or a laser beam printer. It is also possible to monitor the information as a soft copy displayed on the work station 24 instead of the hard copy.
  • the controller 27 controls the entire system, and includes an interface and, if necessary a band compressing and expanding circuit.
  • the controller 27 may be constructed separately as shown in Fig. 4 or integrated with the document reader 22, printer 23, work station 24 or memory 26.
  • the electronic file system can achieve automatic retrieval within several seconds, since a large amount of documents is stored through the document reader 22 into the memory 26 in the form of electrical signals. Also it has a strong advantage of allowing retrieval of the document even immediately after the storage thereof, since the development process as in the conventional microfilm is no longer necessary.
  • microfilm system and the electronic file system have respective advantages as explained before, and the microfilm system cannot be disregarded though the electronic file system has many advantages in consideration of the recent trend of office automation. Consequently the users are either compelled to select either of these two systems or have to endure the inconvenience of using two systems in parallel manner.
  • An object of the present invention is to provide an image file system not associated with the foregoing drawbacks.
  • Another object of the present invention is to provide a file system capable of reading image data from an unerasable image file or from a rewritable image file.
  • Still another object of the present invention is to provide a file system in which a microfilm system and an image disk system are united.
  • Still another object of the present invention is to provide a file system in which retrieving information for reading a desired image from the microfilm and retrieving information for reading a desired image from the image disk are stored in a common index file.
  • Still another object of the present invention is to provide a file system capable of processing large portion of non-code image information.
  • Fig. 5 shows the structure of an embodiment of a united file system according to the present invention.
  • a partial system 28 including the controller 29 corresponds in the present embodiment to the conventional electronic file system shown in Fig. 4, wherein same components are represented by same numbers, but the present invention is not limited to such embodiment.
  • the present invention is featured by a fact that a disk memory 30 and a microfilm file 31 are connected to a same controller 29 and are commonly controlled.
  • Other units such as the document reader 22, printer 23, work station 24 and index file 25 are connected in the same manner as shown in Fig. 4 and will not therefore be explained further. In the following there will be given an explanation on the function of the present embodiment.
  • a large amount of documents is read by the document reader 22 and stored in the disk memory 30, which is random access type as explained before and is preferably composed of a memory of high density and high capacity such as an optical disk memory, for the purpose of space saving.
  • the indexes of the information stored in the memory 30 are stored in the index file 25 and administered by the work station 24.
  • the microfilm file 31 is preferably provided with automatic retrieval function as shown in Figs. 2 and 3, but it can be any type as long as it is equipped with means for converting the image of microfilms into electrical signals by raster scanning.
  • the index of each frame of the microfilms stored in the microfilm file 31 is stored in the index file 25 and administered by the work station 24, in the same manner as the index of the information stored in the memory 30.
  • the index file 25 can be composed of a magnetic disk memory, a floppy disk or a semiconductor memory incorporated in the work station 24.
  • the operator When the operator enters a retrieving condition of the desired information through input means such as a keyboard of the work station 24, it compares the entered retrieving condition with the indexes stored in the index file 25 to indentify whether the desired information is stored either in the memory 30 or in the microfilm file 31, and supplies the controller 29 with the track number in case the information is in the memory 30, or the frame number if the information is in the microfilm file 31.
  • an instruction of the operator to retrieve the information is supplied, through the input means of the work station 24, to the controller 29, which, in response, supplies a read-out signal together with the address of the information either to the memory 30 or to the microfilm file 31.
  • the controller 29 In case the information is stored in the memory 30, it supplies the controller 29 with the information according to the read-out instruction signal and address signal thus entered.
  • the information in case the information is stored in the microfilm file 31, it retrieves the frame of the information according to the read-out instruction signal and frame number thus entered, then converts the two-dimensional image information into electrical signals by raster scanning and supplies the signals to the controller 29 after determined processing.
  • Fig. 6 shows an example of retrieving flow chart which is to be executed by a processor in the work station 24.
  • a keyword is entered as the retrieving condition through the keys of the work station 24 (step 32).
  • an index data base DB stored in a floppy disk 25 is developed in a memory RAM of the work station 24 to form a retrieving table (step 33).
  • step 34 the table data in the RAM are searched according to the entered keyword data (step 34), whereby the number of images meeting the retrieving condition and a list of the images are obtained and displayed on the work station 24 (step 35).
  • step 37 upon entry of a desired index through the keys (step 36), there is identified whether the image corresponding to the index is stored in the microfilm or in the disk (step 37).
  • This operation is achieved by identifying the setting state of data A, which indicates the media of image storage and is stored together with the index data as a part of data base in the RAM.
  • the address data such as the track number in the disk
  • the address data is released (step 38).
  • the address data such as the frame number of the film is released (step 39).
  • step 37 also displays the media in which the image is stored.
  • a discrimination is made whether an image read-out instruction is entered (step 40), and, if affirmative, command data are supplied to the controller 29 to read the image data either from the film or from the disk in which the desired image is stored.
  • the information supplied in this manner to the controller 29 can be processed in the same manner, regardless whether it has been stored in the memory 30 or in the microfilm file 31.
  • the controller 29 can supply the information received from the memory 30 or from the mocrofilm file 31 either to the work station 24 for display as a soft copy on the display unit or to the printer 23 for output as a hard copy.
  • the information of which amount is less than a unit volume of the microfilm file 31 which is a sheet of microfiche in case of a microfiche file or a cartridge in case of a microfilm roll file thus enabling effective use thereof, and to transfer the information to the microfilm when the amount becomes large enough.
  • the information has to be left dead until an economical unit of information is collected since the recording of information less than a microfiche sheet or a microfilm cartridge is uneconomical, but the system of the present invention always allows effective use of information by the method of use mentioned above.
  • the file system of the present invention is provided not only with the advantages of the microfilm system such as a high input speed, archival storage performance, ability for high-speed recordings of a large amount, ability to provide a large-sized image and acceptance as legal evidence, but also the advantages of electronic file system such as a high-speed retrieval, possibility of image retrieval immediately after information input, and ease of image transmission.
  • the operator can retrieve all the information in a single file system, without the trouble of using two systems in parallel taking the time of system shift into consideration.
  • the file system of the present invention enables to add, alter or correct the information freely.
  • the information of coffesponding page is read from the microfilm, subjected to necessary addition or correction and stored then in the electronic file, and the addition or correction of information can be immediately achieved in this manner.
  • microfilms which allow high-speed input of two pages every second in a mirofilming laboratory, and to edit the frequently used information for example in a disk of the memory 30 through the above-mentioned automatic conversion.
  • concentration of frequently used information in one place allows to significantly improve the retrieving speed in comparison with a case where such information are dividedly stored in various media.
